Definitions

  • the invention relates to a roller guide spring having at least one spring element and at least one damping element, in particular a roller guide spring for a roller guide of a lift, wherein the roller guide spring comprises at least one spring element and at least one damping element.
  • Roller guides for elevators typically have rollers that roll on guide rails of the respective elevator and guide a car on a path defined by the guide rails.
  • Each roller guide usually has a roller block, which is rigidly connected to the car or attached thereto.
  • On the roller block is pivotally mounted at least one suspension or a roller lever, which is or is designed as a storage for the rollers.
  • the roller guide each comprises three suspensions or roller lever. By pivoting the roller lever, it is possible to change the position of the roller with respect to the car.
  • the roller mounted thereon can be pressed against or against the respective guide rail.
  • a constant contact of the roller with the guide rail is ensured by the pressing, which is also at an asymmetric load and a resulting skew or inclination of the car and bumps of the Guide rail can be ensured by means of the contact pressure.
  • the contact pressure or the associated contact pressure is usually generated in the previously known roller guides by means of a spiral spring, which sets the roller lever under such a bias that the roller is pressed against the guide rail.
  • a separate damper is usually provided, which dampens a pivoting movement of the roller lever with respect to the roller block. This is particularly necessary during the ride of the car to dampen shocks and spring-back movements of the roller lever after a deflection.
  • a separate mechanical end stop is usually provided, which limits the pivotal movement of the roller lever with respect to the roller block and specifies a maximum possible deflection.
  • the three separate components coil spring, damper and end stop are each separately attached to the roller lever and the roller block and require a correspondingly large space and a high installation cost, since they must be mounted individually.
  • a spring-loaded roller guide with optional damping which provides three roller levers, each with a roller, which acts on the guide rail accordingly from three sides.
  • two of the rollers are arranged opposite each other with respect to the guide rail and act on opposite running surfaces of the guide rail.
  • the pressure forces of the associated roller lever act in opposite directions and cancel each other out in a neutral position of the car.
  • a neutral location describes, for example, an unloaded car at a standstill.
  • a third roller of the described roller guide which is usually arranged between the two opposite rollers is pressed in a neutral position of the car by a compressive force to the guide rail. This is the case since a car usually comprises at least two of the roller guides described, each having a central roller. Their pressure forces are oppositely directed and also cancel each other out in a neutral position of the car.
  • a roller guide which provides a connecting element with a first and a second elastic element in a serial arrangement, wherein a rigidity of the second elastic element increases with a compression of the element.
  • the connecting element does not provide a decoupled damping element for damping the movement of a guide element of the roller guide.
  • a roller guide spring for a roller guide of a lift which comprises at least one spring element and at least one damping element and the damping element is decoupled from the spring element.
  • the at least one spring element and the at least one damping element are integrated or combined in the roller guide spring and the roller guide spring in this way summarizes corresponding functions for generating a compressive force and a damping of a vibration in a single module.
  • the spring element and the damping element is designed to be decoupled from each other. Decoupling here means, in particular, different dependencies of the individual elements of physical quantities. While a spring action of the spring element is dependent on a deflection or a compression of the spring element or the roller guide spring and thus on a path, a damping effect of the damping element is dependent on a current speed or a speed of a deflection change of the roller guide spring. Thus, a momentary speed or a compression or expansion speed of the roller guide spring is decisive for the damping element.
  • the roller guide spring may be formed as a cylinder with at least one piston displaceable therein, in which a fluid is compressed and / or displaced is, comparable to a pressure piston or a so-called strut.
  • a fluid for example, any suitable gas or liquid or a combination of both types of fluids can be used.
  • a fluid intended for compression must be compressible.
  • suitable springs of various shapes such as coil springs, as a spring element possible to generate the pressure force or the spring action.
  • a combination of springs and one or more fluids can be used.
  • spring assemblies with progressive characteristics and / or use of a compressible solid which may have elastic deformation properties, such as rubber or foam.
  • the term provided for generating a spring action spring element is to be understood a spring means which provides both a device for the immediate provision of a spring action and an arrangement or device of other devices that indirectly provide a spring action due to their arrangement.
  • the spring element may also comprise a corresponding arrangement of components or devices suitable for providing a spring action. This can be achieved, for example, with the above-mentioned compression of a fluid. Basically, however, the spring action achieved, as above shown, path-dependent and thus the spring force proportional to a spring travel.
  • the damping element provided for generating a damping effect is to be understood as meaning a damping device which can provide both a device for explicitly providing a damping effect and an arrangement or device of other devices which provide a damping effect due to their arrangement.
  • the damping element may also include an assembly of components capable of providing a damping effect. This can be done, for example, by the above-mentioned displacement of a fluid.
  • a damping element is to be understood in both cases as meaning a construction or an arrangement of components which, due to targeted measures and configurations, causes the damping of a movement.
  • the damping element is not to be understood as a buffer, which essentially has a stop with a certain damping or self-damping and buffers a movement only in a region just before the stop.
  • the described damping element may be provided to dampen movement of the roller guide spring at least in a large portion of its range of motion or even in its substantially full range of motion.
  • the damping effect of the damping element depends on the speed of the deflection change of the roller guide spring and not on the actual deflection (as position) of the roller guide spring.
  • the damping element thus provides a damping effect both during compression and during expansion of the roller guide spring. This damping effect is proportional to the instantaneous deflection change or the compression or expansion speed of the roller guide spring.
  • the roller guide spring also comprises a stop element.
  • the stop element comprises at least one mechanical stop.
  • an end stop can be realized by a mechanical blockage in or on the cylinder.
  • any other suitable form of the stop is possible, which is suitable to realize a stop or a blockage in the cylinder.
  • a spring characteristic of the at least one spring element on a progressive curve or a progressive spring characteristic Contrary to the usual in coil springs linear characteristic of the spring characteristic, which describes a linear increase of the spring force on the deflection, a progressive curve represents a disproportionate force increase with increasing magnitude deflection. Thus, with a small deflection, a low compressive force and a large deflection a large pressure force can be achieved. This offers the possibility that even a small spring force and thus a low reaction force or restoring force occurs at a small deflection, which also acts on the car.
  • the progressive characteristic and thus the driving behavior of the car is therefore more tolerant of small bumps of the guide rail and thus the car experiences even lower restoring forces, which benefit the comfort of passengers.
  • the contact pressure at small deflections and in particular in the neutral position can be significantly reduced.
  • the rollers experience a significantly lower contact pressure or a lower contact pressure on the guide rail at standstill of the car.
  • the consequent flattening of the rollers can be significantly reduced in this way, whereby the vibrations and running noise caused thereby and the excessive wear during operation can be reduced.
  • a rocking of the car is prevented.
  • the correspondingly increasing force with increasing deflection counteracts the development of a rocking motion.
  • the spring element is therefore independent of its actual configuration designed such that its spring characteristic corresponds to a compression spring with progressive characteristic.
  • the spring element for changing the spring action is adjustable and the spring characteristic or the curve of the spring characteristic variable.
  • the spring characteristic or the curve of the spring characteristic variable can be changed by the change in the pressurization of the fluid, in particular a gas pressure, the spring action of the spring element. If, on the other hand, springs are used, suitable measures for altering or changing the spring action must be provided for this purpose.
  • the adjustability of the spring element characterizes in particular the property that the setting without large and extensive Assembly effort can be performed. It should, for example, an exchange of components become unnecessary. This is achieved, for example, by the said change in the pressurization of the fluid and, in particular, allows a simple change which can easily be carried out on site.
  • such adjustability allows infinite adjustment or adjustment, which is particularly suitable for a reproducible adjustment of specific parameters of the spring element. For example, it is possible to change the slope of the characteristics and thus a corresponding increase in force by moving the operating point of the fluid in the neutral position of the car.
  • the damping element for changing the damping effect adjustable and a damping characteristic of the damping element can be varied.
  • the damping can be changed, as for example by a change in size of passage openings for the fluid.
  • the adjustability of the damping element is to be understood here as a property according to the above description of the adjustability of the spring element and also allows easy adjustment on site, which can be made continuously and reproducibly. Basically, there is no linkage or coupling between the spring element and the damping element with regard to their adjustability. Both elements are rather independently adjustable.
  • the progressive curve of the spring characteristic may be provided by a suitable execution of a kinematics of the roller guide.
  • the kinematics of the roller guide eccentric bearings which includes a disproportionate increase in the restoring force or the spring force against the deflection provides.
  • the roller guide spring comprises at least one sensor.
  • the at least one sensor can be designed such that a deflection or a change in length of the roller guide spring in a longitudinal direction of the roller guide spring can be determined by means of the at least one sensor.
  • the at least one sensor may comprise at least one pressure sensor.
  • the described roller guide spring is intended for installation in a roller guide of an elevator.
  • the roller guide of a car in this case comprises a roller block and at least one suspension, which is arranged movably on the roller block and designed for the storage of at least one roller.
  • the roller guide comprises the at least one roller guide spring, which is operatively connected to the suspension and the roller block, wherein the roller guide spring comprises the at least one spring element and the at least one damping element and the damping element is decoupled from the spring element.
  • the at least one suspension may comprise at least one roller lever, which is arranged pivotably on, for example, the roller block of the roller guide.
  • the roller guide comprises the above-described roller guide spring, wherein a position of the suspension or the roller with respect to the roller guide by means of the at least one sensor can be determined.
  • roller guide may comprise devices for reading out and providing a sensor signal of the at least one sensor.
  • the at least one sensor comprises a pressure sensor
  • the pressure of the fluid for example the gas pressure
  • at least one spring element and / or the at least one damping element of the roller guide spring can be measured and based on the pressure of the fluid on the deflection or closed the change in length of the roller guide spring and the above conclusions are derived.
  • the spring element for changing the spring action and / or the damping element for varying the damping effect can be adjustable and the roller guide also comprise means for adjusting the spring element and / or the damping element.
  • the devices for adjusting the spring element and / or the damping element are formed to a pressure change in the spring element and / or in the damping element.
  • the pressure of the fluid can be changed by means of the adjusting means and can be adapted to corresponding requirements.
  • This allows quasi a touch of a button by adjusting the pressure in the roller guide spring to change a suspension tuning. This can be done to adapt the landing gear to the appropriate type of elevator or even to tune continuously during regular operation.
  • the adjustment of the spring element and of the damping element takes place in principle independently of each other, so that a targeted adaptation or adjustment of at least one of the two elements is possible.
  • An adjustment of the damping element is further, for example, by a change in the viscosity of the respective fluid or by means of cross-sectional changes of openings for the fluid possible.
  • the devices for adjusting the spring element and / or the damping element comprise, for example, a pressure supply.
  • This can further be formed as a central pressure supply to a pressure reservoir and thus allows a central control of the roller guide spring or more roller guide springs.
  • the aforementioned adjustability of the at least one spring element and / or the at least one damping element provides in addition, the ability to easily adapt a suitable embodiment of a roller guide spring for various elevators and a wide range of elevator types without having to make structural changes. Rather, the roller guide spring can be individually adjusted on site according to the needs of the respective elevator.
